Foreshock wave interaction with the magnetopause: Signatures of mode conversion 

Shi, Feng; Cheng, Lei; Lin, Yu; Wang, Xueyi; 0000-0001-8003-9252; 0000-0001-5533-5981 (2020-06-01)
Our previous hybrid simulation (Shi et al., 2013) under a radial interplanetary magnetic field (IMF) and a supercritical solar wind Mach number has shown that foreshock compressional waves originated from the quasi-parallel ...

Global hybrid simulation of mode conversion at the dayside magnetopause 

Shi, Feng; Lin, Yu; Wang, Xueyi (2022-09-28)
Mode conversion at the magnetopause has been suggested to lead to the generation of kinetic Alfven waves (KAWs) and effective mass transport from the solar wind into the magnetosphere. To investigate the mode conversion ...

Modeling of a New Electron Acceleration Mechanism Ahead of Streamers 

Ihaddadene, Kevin M. A.; Dwyer, Joseph R.; Liu, Ningyu; Celestin, Sebastien; Shi, Feng (2020-05-26)
Head‐on collisions between negative and positive streamers have been proposed as a mechanism behind X‐ray emissions by laboratory spark discharges. Recent simulations using plasma fluid and particle in cell models of a ...

VHF and UHF Electromagnetic Radiation Produced by Streamers in Lightning 

Shi, Feng; Dwyer, Joseph R.; Ihaddadene, Kevin M.A.; Liu, Ningyu; https://orcid.org/0000-0003-3406-9383 (2020-03-10)
In this letter, we report simulation results of streamer propagation and collision that produce electromagnetic radiation in the very high frequency (VHF) and ultra high frequency (UHF) bands. The streamers are initiated ...
